I need help for this problems

    I need help for this problems!!!

    A car enters a curve in the road with a speed of 24 m/s and emerges from this curve 20 s later with the same speed. However, the direction of the velocity changes by 60 degrees during this time.
    What is the magnitude of the average acceleration during this time interval?

    I don't understand the situation, can someone please explain me??

    Hi KeEsA, welcome to PF!:smile:

    In the future, problems like this should be posted in the introductory physics HH forum.

    I'm not sure which part you don't understand...Are you confused as to why there is any acceleration when the speed doesn't change? Or are you just unsure as how to visualize the problem?
